Abstract (en)
[origin: EP3872917A1] The present invention relates to a method for manufacturing a secondary battery with improved resistance. Since an electrode assembly with succinonitrile interposed at an interface between an electrode and a separator is manufactured and then laminated, a high-pressure process is not required during lamination in contrast to conventional technology, such that processability is improved; and since succinonitrile is dissolved in an electrolyte, battery resistance is improved.
